.change your pee into petrol.

Researchers in Singapore have developed a paper battery that is powered by urine. Despite sounding gloriously silly, the breakthrough promises a cheap and disposable power source for home health tests for things like diabetes.

The battery is composed of paper, soaked in copper chloride, sandwiched between layers of magnesium and copper. The whole thing, once laminated in plastic, is just a millimetre thick, and 6cm by 3cm in size.
